FM calibration parameter
Output of terminal HDO with FM function can be shown as follows:
2300Hz
0
1440Hz
FM Pulse frequency
Corresponding to 100% of the
function set by 02-44
(
P.543
)
Terminal HDO needs to be calibrated due to differences in components, voltage/current calibration includes the
following steps:
1. Link an electric meter with 1mA scale or a high speed counter across terminal HDO and terminal SD. Wire as
following figure , and set 02-51(P.55) to 60Hz,02-44(P.543) to 0.
2. Start the motor and set output frequency 60Hz.
3.When the motor runs steadily, read out 02-59(P.187) value. Display will show FM calibration value. Press
